METHOD AND APPARATUS FOR MEASURING TRUE TRANSMITTED POWER USING A BROADBAND DUAL DIRECTIONAL COUPLER

摘要

A dual-directional coupler (100) for measuring true RF power (104) apparent at a radiating element. Incident and reflected power are detected by a pair of detectors (201, 202). The difference between the two detected voltages (201, 202) is amplified by a differential amplifier (203) to generate a voltage proportional to the true transmitted power.
